Having a self-conscious narrator who is obsessed by the question of art-truth relationship, The Black Prince is the paradigm of metafiction among Iris Murdoch's works. A discourse about the problems of writing fiction, the novel actually exposes the ontological status of all literary fiction, i.e. its quasi-referentiality, its indeterminacy and its existence as a linguistic world. This paper argues that more than being a thematic concern, metafiction is the integral part of The Black Prince whose fragmented form mirrors the complexity of reality. It concludes that such a full-fledged metafictional project does not resonate with the anti-fictional convictions but aspires to validate metafiction as the perfect moral form of fiction.
